JOSEPH AMY Axr, or 'AMBoY, MINNEsoTA GRAIN-BOARD HOLDER.

Specification of Letters Patent.

Application led October 7, 1919. Serial No. 329,068.

To allwhom t may concern:

Be it known that I, JOSEPH A. Axr, a citizen of the United States,residing at Amboy, in the county of Blue Earth and State of Minnesota,have invented a new and useful Grain-Board Holder, of which thefollowing is a specification.

This invention contemplates the provisionl of improved means for holdingthe door boards in position in a grain car.A

Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood, that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 is a vertical sectional view of agrain car equipped with my improved grain door and board holder.

Fig. 2 is a horizontal sectional view, and

Fig. 3 is a transverse fragmentary sectional view on theline 3-3 of Fig.1.

Fig. 4 is a Perspective view showing one of the levers.

The numeral 10 designates a car having a floor 11 and a ceiling 12. The'door open; ing is designated at 72 and at each side of the door openingare arranged the door posts 14.

Instead of nailing the boards 15 to the posts or frame 14, there isprovided at the inner face of one door-post a vertical shaft 16 havingan obtuse angular clamping jaw 17 rigid therewith and extending theentire height of the opening 72, the upper end of the shaft beingpivotally suspended from the top of the car by means of a hanger 18, soVthatv the shaft can swing in a vertical plane on a pivot 19, and rotateon an axis 18.

The lower end of the shaft 16 extends through a slot 20 in the floor 11so as to allow the swinging movement above set forth. In order toprevent escape of the grain through the slot 20, there is mounted on theshaft a plate 21 which operates in a recess 22 in the floor.

The jaw 17 is normally held in a clamping position by means of acontractile coiled spring 23 which is secured to the car frame, theshaft being extended below the floor. There is mounted on the shaft 16 alever 24 having connection with the spring 23.and provided with apivoted handle 50, pivotally mounted as at 25, so that it may be swungdownwardly, out of the way. A similar lever 26 is slotted as at 51 andis slidably mounted on the shaft 16 and is intermediately fulcrumed onthe car as shown at 27, the inner end of the lever being connected Vto acontractile coiled spring 28 anchored to the car frame, so that theshaft 16 may be shifted in the slot 20. By means of the lever 24, theshaft 16 may be rotated the jaw 17 being moved out of clamping positionwith respect to the door boards 15, and the lever 26 has a handleportion 52 to swing downwardly like the handle 50 of the lever 24. Thelever 26 is for the purpose of swinging the shaft 16 to cause the boards15 to clear the edge of one of the posts 14 so that the grain pressingagainst the boards from the inside will press one end of the boards outand so release the grain. When the jaw 17 is pressed against the boards15, the handles of the levers can be moved downwardly to verticalpositions at the edge of the car and held by pins 29.

At the opposite side of the door opening there is arranged a crank shaft30 having its ends 31 and 32 mounted to rotate in the top and the floorof the car respectively. To the lower end of the shaft 30 there isattached an arm 33 which by means of a spring 34, connected thereto andto the floor of the car, holds the offset portion of the shaft 3() inengagement with the adjacent ends of the boards 15. The shaft 30 rotatesand releases the boards at one end, when the other end of the boardsswing outwardly through 'the doorway as hereinbefore described.

Having thus described the invention, what is claimed is y y 1. A graindoor holder comprising a shaft having an offset jaw; means for mountingthe shaft at its upper end for axial rotation and for swinging movementin a vertical plane; spring means for rotating the shaft in onedirection; means under the control of an operator for rotating the shaftin an opposite direction; and means for imparting swinging movement tothe shaft.
